The new design about a CW
digital all-solid-stated LD pumped Nd:YVO 4 controller is introduced. The stable output power of this digital laser controller which adopts Digital Signal Processor(TMS320C31) is approximately 20mW. The whole system is composed of constant- current source
protection circuit
pulse-width modulation circuit
Si-photo-detector and amplified circuit and Digital Signal Processor control system
etc. In terms of error deviation Based on nonlinear control curves of LD power output by Si-photo-detector
the region control can be obtained by means of the PID control algorithm in the software platform
that is
error amendment and high stability laser power output can be achieved. And the precision of temperature control can reduce from 0.2C to 0.04C. By adopted integral separated mode PID control algorithm
the LD output power instability ( %) down to 2%. By way of adopting the new digital design
the work to protect the laser diode
including the continuous adjustable output power with high accuracy and stability
is easily obtained. The internal-external modulation control of the laser power based on digital optical feedback can be accomplished with stable power output. At last
the bringing reasons of noise are analyzed and the solving methods are put forward in this paper.
